Nährstoffversorgung zur Optimierung der N2-Fixierung und Produktivität von Körnerleguminosen
Seehuber, Claudia (2015-01-26)Erstes Ziel der vorliegenden Arbeit war es, eine ausbalancierte optimale Nährstoffversorgung von Ackerbohnen (Vicia faba) mit einer einhergehenden maximalen Stickstoff-Fixierung auch auf biologisch bewirtschafteten ... -
A new approach for a kinematic-dynamic determination of low satellite orbits based on GNSS observations
Shabanloui, Akbar (2008)A new approach for the integrated kinematical-dynamical orbit determination of low flying satellites based on high-low GPS-SST observations is proposed. These observations are code and carrier phase measurements between ... -

Nitric oxide synthase (NOS) genes expression in cattle in vitro produced embryos
Kadanga, Ali Kpatcha (2005)This study was conducted to determine whether NOS-NO affects oocytes meiotic maturation and embryo development in vitro in bovine, to profile the temporal expression pattern of NOS genes, then to detect and localize ... -
Nitrogen management in irrigated cotton-based systems under conservation agriculture on salt-affected lands of Uzbekistan
Devkota-Wasti, Mina Kumari (2011-11-23)Intensive soil tillage and mismanagement of irrigation water and fertilizers reduce soil organic matter and increase secondary soil salinization. These processes are increasing production costs, reducing soil fertility and ... -
Nitrogen sequestration in paddy and non-paddy soils formed from different parent materials
Houtermans, Miriam (2019-08-19)Paddy soils exhibit low nitrogen (N) use efficiency. Prior research in this field suggested that paddy soils may sequester significant amounts of N in aged amino acids, microbial residues, or even in pyrogenic N. The ... -
Non-destructive evaluation of complex interactions between Heterodera schachtii and Rhizoctonia solani on sugar beet as affected by cultivar resistance
Hillnhütter, Christian (2011-02-08)The beet cyst nematode Heterodera schachtii and Rhizoctonia crown and root rot caused by the fungus Rhizoctonia solani anastomosis group 2-2IIIB were investigated for the presence of synergistic interactions on sugar ... -
Non-invasive monitoring of water and solute fluxes in a cropped soil
Garré, Sarah (2010-12-15)Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and ... -
NRF2 mediated oxidative stress response activity during early in vitro bovine embryo development
Amin, Ahmed Abdelsamad Zaki (2015-03-30)Overcoming oxidative stress is one of the various embryo challenges to survive under suboptimal conditions during in vitro production of bovine embryos. Thus, the present study aimed to examine the ability of preimplantation ... -
